Vital2AI: The Bridge Between Your Health and AI. Vital2AI is a specialized utility designed for health enthusiasts, researchers, and AI early adopters. It solves the "locked data" problem by allowing you to export your comprehensive Apple Health history into clean, structured, and AI-ready CSV files. WHY VITAL2AI? While Apple Health provides a great dashboard, it’s difficult to analyze trends or feed data into LLMs like Gemini or ChatGPT. Vital2AI bridges this gap by converting complex HealthKit data into a flat, readable CSV format. KEY FEATURES: - 90+ Health Metrics: Export everything from steps and heart rate to advanced nutrition, sleep stages, and respiratory data. - Individual Workout Export: Dedicated CSV for workout history including duration, heart rate zones, and effort scores. - AI-Ready Format: CSVs are specifically structured for easy ingestion by AI agents and data analysis tools. PRIVACY & TRANSPARENCY: - 100% Open Source: Our code is public. Anyone can verify how we handle your data. - On-Device Processing: All CSV generation happens strictly on your iPhone. - No Data Collection: Your data never leaves your device unless you choose to share it. No servers, no trackers, no ads. - Biometric Security: Protect your exports with FaceID or TouchID. Disclaimer: Vital2AI is for informational and research purposes only and is not a substitute for professional medical advice.
